A transducer assembly is presented. The transducer assembly includes an acoustic layer having a first side and a second side, opposite the first side. Furthermore, the transducer assembly includes at least one matching layer disposed on the first side of the acoustic layer. Additionally, the transducer assembly includes a dematching layer disposed on the second side of the acoustic layer, where the dematching layer has an acoustic impedance greater than an acoustic impedance of the acoustic layer, and where the transducer assembly does not include a backing layer that is highly attenuative. |
